To prime or not to, that is the question.

This is my everyday-face and that's my everyday companion - Iggy's toys. Scattered around the house but more often than not, the serve as an inspiration. The colors, the clashes, the fun.
The color of the car? I have an eyeshadow that shade and of course, I have not only one but two nailpolishes identical to it. One creme and one with glitter. But, do I wear it all?
No, not as often as I would like. Most of the time I'm stuck in a rut. My Joan Jett-rut with pale face and lot's of black around the eyes.

I need to find some other style-icons. While I love Shrinkle's use of color, I am well aware that it would never last on me. A trip to the dogpark later and I would look like a spit out gummibear.

My (obvious) option would be using a primer, but I feel like that is a waste of money. That it's yet another product the companies have lured us into thinking we need.
Is it?
